Step 2 - Fit cage nuts
Fit cage nuts in the correct positions to match the screw holes in the APS rack
mounting brackets.
Step 3 - Mount the APS
1
Remove the ground connection bolts on the sides of the APS to allow clearance to
mount in rack.
2
Lift the APS to the correct position in the rack.
A suitable mechanical support or a second person must support the weight of the
APS.
3
Attach the APS using four rack mounting screws. Tighten the screws.
Step 4 - Grounding
The grounding arrangement of your communications equipment determines how the
dc common bus of the dc power system is referenced to ground.
There are two options, Either:
the dc supply is referenced (bonded) to a telecom ground electrode (Step
4A), or
the dc supply is referenced (bonded) to the ac ground, via the chassis (Step
4B).
The APS is supplied with the dc common bar bonded to the chassis via a link on the dc
common bar.
